TLDR
The existence of a new U(1) gauge coupling is considered in this paper, where the coupling is constrained by the demand that the model be anomaly free and that the right-handed neutrino not be light.About:

Journal ArticleDOI
Nonexotic Neutral Gauge Bosons
TL;DR: In this paper, the authors study theoretical and experimental constraints on electroweak theories including a new color-singlet and electrically neutral gauge boson, and derive bounds on the mass and couplings imposed by direct production and Z-pole measurements.
Journal ArticleDOI
Lepton Number Violation: Seesaw Models and Their Collider Tests
TL;DR: In this paper, the authors consider a number of representative Seesaw scenarios as phenomenological benchmarks, including the characteristic Type I, II, and III Seeaw mechanisms, their extensions and hybridizations, as well as radiative constructions.

Stellar cooling bounds on new light particles: plasma mixing effects
Edward Hardy,Robert Lasenby +1 more
TL;DR: In this article, the authors make an updated estimate for the stellar cooling bounds on light scalars and vectors with a variety of SM couplings, and significantly change the mass dependence of stellar bounds on new vectors.
Journal ArticleDOI
Serendipity in dark photon searches
TL;DR: The authors developed a framework for recasting dark photon searches to obtain constraints on more general theories, which includes a data-driven method for determining hadronic decay rates, which can be generalized to any massive gauge boson with vector couplings to the Standard Model fermions.
BookDOI
The Dark Photon
TL;DR: The dark photon is a new gauge boson whose existence has been conjectured as mentioned in this paper, and it is dark because it arises from a symmetry of a hypothetical dark sector comprising particles completely neutral under the Standard Model interactions.

Measurements of attractive forces between flat plates
TL;DR: In this article, a description of the apparatus used to measure the attraction between flat metal plates is given, and an explanation of results of earlier measurements made by the author on attraction between clean, and also between silvered glass and quartz plates, all brought in an ionized atmosphere is suggested.

Primordial nucleosynthesis: a critical comparison of theory and observation
TL;DR: In this article, the nucleon-to-photon ratio of primordial nucleosynthesis is re-examined in the context of a detailed comparison of theory and observation, and a new argument is presented to show how the observed abundances of D and /sup 3/He can be used to derive a lower bound to the nucleus density.

The equivalence of inertial and passive gravitational mass
P. G. Roll,R Krotkov,R. H. Dicke +2 more
TL;DR: In this article, the results from the most sensitive torsion balance used enable the authors to conclude with 95% confidence that |η(Au, Al)| = 0.

Detection of anti-electron-neutrino e Scattering
TL;DR: In this paper, a 15.9-kg plastic scintillation target in a composite plastic-NaI-liquid detector was exposed to a nu-bar/sub e/ flux of 2.2 x 10/sup 13/ cm/sup -2/sec/sup 1/1/

A theoretical and experimental review of the weak neutral current: a determination of its structure and limits on deviations from the minimal SU ( 2 ) L × U ( 1 ) electroweak theory
TL;DR: In this paper, a detailed analysis of existing neutral-current data has been performed in order to determine as fully as possible the structure of the hadronic and leptonic neutral currents without recourse to a specific weak-interaction model.
